Earth's Moon is the brightest and largest object in our night sky. The Moon makes Earth a more livable planet by moderating our home planet's wobble on its axis, leading to a relatively stable climate. It also causes tides, creating a rhythm that has guided humans for thousands of years.
The Moon is the second-densest satellite in the Solar System, after Io. [ 76] However, the inner core of the Moon is small, with a radius of about 350 kilometres (220 mi) or less, [ 1] around 20% of the radius of the Moon.
La Luna es un satélite excepcionalmente grande en comparación con su planeta, la Tierra: un cuarto del diámetro del planeta y 1/81 de su masa. 4 Es el segundo satélite más grande del Sistema Solar en relación con el tamaño de su planeta, siendo Caronte el más grande en relación con el planeta enano Plutón.
The Moon is Earth's only natural satellite. It goes around the Earth at a distance of about 239,000 miles (385,000 kilometers). The Earth and Moon are tidally locked. Their rotations are so in sync we only see one side of the Moon. Humans didn't see the lunar far side until a Soviet spacecraft flew past in 1959.
The Moon can be seen in the daylit sky at any phase except for the new moon, when it’s invisible to us, and full moon, when it’s below the horizon during the day.
24 de ago. de 1998 · Moon, Earth’s sole natural satellite and nearest celestial body. Known since prehistoric times, it is the brightest object in the sky after the Sun. Its name in English, like that of Earth, is of Germanic and Old English derivation.
21 de ago. de 2024 · Earth has just one moon – a rocky, cratered place, roughly a quarter the size of Earth and an average of 238,855 miles away. The Moon can be seen with the naked eye most nights as it traces its 27-day orbit around our planet.
From your astronaut’s viewpoint, you can see that the Moon is an average of 238,855 miles (384,399 km) from Earth, or about the space that could be occupied by 30 Earths. It travels around our planet once every 27.322 days in an elliptical orbit, an elongated circle.
The Moon makes a complete orbit around Earth in 27 Earth days and rotates or spins at that same rate, or in that same amount of time. Because Earth is moving as well – rotating on its axis as it orbits the Sun – from our perspective, the Moon appears to orbit us every 29 days.
4 de oct. de 2017 · As the bright parts of the Moon appear to change shape during the month, each stage of the change is called a phase, and each phase carries its own name. This chart shows why this happens. The center ring shows the Moon as it revolves around the Earth, as seen from above the north pole.
